"...this is a book to be read and reckoned with. The comparison between Germany and Italy is compelling, often leading one to see each country's experience in a different light. The insights into the dynamics of violent social movements, particularly those regarding the role of the police and the ways that groups and individuals move into terrorism are trenchant and original. In general, the book demonstrates the effectiveness of using an institutional approach for studying political violence." Ted Perlmutter, German Politics and Society
